Phys. Rev. D 62, 024002 (2000) [14 pages]Mesoscopic fluctuations in stochastic spacetimeReceived 18 January 2000; published 1 June 2000 Mesoscopic effects associated with wave propagation in spacetime with metric stochasticity are studied. We show that the scalar and spinor waves in a stochastic spacetime behave similarly to the electrons in a disordered system. Viewing this as the quantum transport problem, mesoscopic fluctuations in such a spacetime are discussed. The conductance and its fluctuations are expressed in terms of a nonlinear sigma model in the closed time path formalism. We show that the conductance fluctuations are universal, independent of the volume of the stochastic region and the amount of stochasticity. © 2000 The American Physical Society URL:
